Overview

Description

BTS728L2 is a two-channel low-side smart switch from the BTS family (Infineon). It provides protected switching for two independent automotive loads with built‑in MOSFETs and diagnostic feedback. Key features typically include:
- Independent low-side outputs for two loads
- Protection: short-circuit to ground, overload/current limit, over/undervoltage, overtemperature, and reverse polarity
- Open-load detection and diagnostic/status reporting to a microcontroller
- TTL/CMOS-compatible control inputs (often with enable)
- Designed for automotive supply ranges (roughly 6–28 V) and harsh automotive environments
Typical uses: automotive actuators and lamps (motors, relays, solenoids, etc.), where protected, simple control and fault feedback are valuable. The device simplifies MCU interfacing by integrating protection and diagnosis, reducing external components.

Package

Power-SSO-16 (PG-SSO-16) package — 16-pin, leadless with exposed pad (2-channel BTS728L2 version).

Pinout

- Pin count: 8 pins
- Function: Automotive dual high-side smart switch. Provides two independent load switches (IN1/OUT1 and IN2/OUT2) from VBAT to loads, with built-in current limit, short‑circuit/overtemperature protection, and diagnostic/status feedback.

Manufacturer

Manufacturer: Infineon Technologies AG.
About the company: Infineon is a German multinational semiconductor manufacturer that designs and produces integrated circuits and system solutions, specializing in automotive electronics, power semiconductors, security ICs, and industrial microelectronics.

Application

BTS728L2 is a smart high-side switch for automotive 12/24 V systems with protection and diagnostics. Typical applications include:
- Automotive body electronics: lighting, wipers, power windows, seat/motor actuators
- Door modules and HVAC actuators
- Industrial/ Commercial 12/24 V loads: DC motors, pumps, solenoids
- ECU protection roles: load switching with overcurrent, short to GND/Vcc, overtemperature diagnostics

Equivalent

BTS728L2 is Infineon’s automotive high-side switch (load switch) with protections and diagnostics. There isn’t a single exact cross-reference. Closest equivalents are other vendors’ automotive high-side switches with similar current ratings (e.g., TI TPS1H/Q1 family, Onsemi NCP series, ST ST1S/STx family). For precise equivalents, provide target load current, input voltage range, package, and whether diagnostic is required.
